Applicati'on filed March12, 1917. Serial No. 154,232.

To allwhonmtmay concern: 7 I 1 Be it known that I, OLIVER'R. HADLEY, a

citizen of the United States, residing at Bradford, in the county ofMerrimack, State of New Hampshire, have'inve'nted certain new and usefulImprovements in Env'elop Closures; and I do hereby declare the followingto be a full, clear, and exact description of the invention, suchas'will enable others skilled in the art to whioh'it appertains to makeand use the same.

This invention is an improvement in paper receptacles and has particularreference to an envelop closure.

An object of the invention is to provide an improved closure which willeflectively prevent an envelop from becoming acc dentally opened bycontact with other mail or otherwise, and, to this end, use is made of apair of eccentrically mounted disks adjustable relative to each other toengage the closure flap of an envelop and retain the same in closingposition.

Another object is the provision of an improved closure of this characterwhich s simple in construction, easy to manufacture and effective incarrying out the purpose for which it is designed.

The inventive idea involved 18 capable of receiving a variety ofmechanical expressions, one of which, for the purpose of illustratingthe present invention, is shownin the accompanying drawing, whereinFigure 1 is a plan view of an envelop showing the closure device inclosing posilieved to be a' preferred form of the invenand likearticles,

tion which is used in connection with envelops for containing circulars,catalogues but it will of course be understood that the same may also beemployed with envelops of other characters.

The envelop 5 is provided with the usual closure fiap6 which has anopening 7 there- 'Adjacent the opening of the envelop the same hassecured theretoa rivet 9 consisting of ahead 10 andprongs 11 whlch areadapted to be projected through the body of the envelop and bent over soas to secure said rivet in positionj The inner side ofthe headispreferably provided with the ribs 12 extending diametrically on eachside of the shank of the rivet for a purpose which will presentlyappear.

A relatively stationary disk or looking member 13 iseccentricallymounted upon the shank of the rivet and has associated therewith arotatable disk or looking member 14 which is likewise eccentricallymounted upon the rivet. and interposed between the head thereof and saiddisk 13.

When it is desired to close the envelop the disk 14: is rotated untilthe periphery thereof registers or is flush with the disk 13. Th closureflap '6 is then folded over, and the opening 7, which is of a slightlylarger diameter than the disks l3 and 14 will receive said diskstherein. Then by rotating the disk 14, the same will be caused to assumea position as shown in Fig. 1 whereupon the closure flap will belockedin position and in order to prevent the same from accidentally comingopen the ribs 12 of the head of the rivet are caused to frictionallyengage the adjacent surface of the disk 1 L so that the same will beprevented from freely turning on its pivot.

lVhat is claimed is l. The combination with an envelop having a closureflap provided with an opening, of a closurevdevice for said flapincluding relatively adjustable and eccentrically mounted disks whichextend through the opening in said closure flap when the same is inclosing position, one of said disks being adjustable to overlap saidclosure flap and prevent opening thereof.

2. The combination with an envelop having a closure flap provided withan openin a rivet carried by said envelop, a stationary diskeccentrically mounted upon said rivet, and an adjustable diskeccentrically mounted upon said rivet and movable to overlap saidclosure flap when the same is in closing position to prevent openingthereof, the opening in said closure flap receiving said disks when theflap is adjusted to closing position.

3. The combination with an envelop having a closure flap provided withan opening, a rivet carried by said envelop, a stationary diskeccentrically mounted upon said rivet, an adjustable disk eccentricallymounted upon said rivet and I movable to overlap said closure flap whenthe same is in cl'os ing position to prevent opening thereof,

of said ri et and 'frictionally engaging said ad jiisfiable disk toresist adjustment thereofl 4. An envelop including 21 body hearing; aclosure flap therefor provided With an opening, a,. lockin device forthe flaip including relatively adg ustable disks one 015 which passesthrough the opening' in the. closure when the same is moved toilosingposition whiie the other engages 111 said opening when thealoclnngdexzlee is ln operative position, the first named disk being adjustableto overlap the closure flap and prevent opening thereo testimonywhereof, I afiix my; signature in the presence of two Witnesses.
